When an internet request and response occurs, a Content-Type header is
passed. A mimetype, also referred to as MIME type, identifies how the content
that is being returned should be handled or used, based on type, by the
application and browser. A MIME type is made up of a MIME group (i.e.
application, image, audio, etc.) and a MIME subtype. For example, a MIME
type is image/png where MIME group is image and subtype is png.
As types may contain vendor specific items, a
custom vendor specific MIME type,
vnd, can be used. A vendor specific MIME type will contain vnd such as
application/vnd.jupyter.cells.
